Abstract (en)

Complex electronic circuits are subjected to a test procedure to identify faults that are then subjected to a repair process. The measured parameters values obtained during testing are subjected to fault classification process that results in the establishment of fault vectors. Two fault vectors are determined for small and large out of tolerance conditions respectively. The two sets of vectors are then subjected to analysis to control the repair process.

Abstract (de)

Die Schaltungsmoduln werden vor ihrer Vereinigung zu einer Baugruppe wenigstens einer betriebstechnischen Prüfung unterworfen. Die Meßwerte der dabei durchgeführten Meßreihen werden zur Fehleranalyse mit jeweils konkreten Fehlerursachen entsprechenden in einem Speicher abgelegten Wertegruppen (Fehlervektoren) verglichen.
